Important

Read these directions for use carefully in order to obtain accurate measuring results.

This blood pressure monitor is only suitable for measuring the blood pressure of adults.

This blood pressure monitor measures blood pressure on the basis of the pulse rate. If you have a very weak or irregular pulse, the blood pressure monitor may not be able to determine the right blood pressure value.

Diabetics and people who suffer from cardiac arrhytmia, vascular constriction or liver disorders must consult their doctor before they start measuring their own blood pressure, since their blood pressure values might deviate from normal values. Pregnant women should also consult their doctor first.

If in doubt, consult a doctor.

Only a doctor is capable of interpreting your blood pressure values. Never change your medication without consulting a doctor.

Your blood pressure may fluctuate during the day and it may even vary within minutes.This means that successive measurements may show different values.

If the blood pressure monitor has been stored at a very low temperature (close to freezing point), put it in a warm place for at least one hour before using it.
